Introduction
3.1
Description The extension module AMC2-4WE is equipped with four Wiegand type reader-interfaces plus eight inputs and eight outputs. Hence with the AMC2-4WE it is possible to double the number of readers on an AMC2-4W from 4 to 8.
Figure 3.1: The extension module AMC2-4WE
The AMC2-4WE can not be deployed as an independent controller but only as an extension module for the AMC2-4W. Control and access decisions and bookings are carried out by the AMC2-4W alone. Notice! The AMC2-4WE can only be used with AMC2-4W. As it provides Wiegand interfaces it cannot be coupled with an AMC2-4R4. The AMC2-4W can be extended by a maximum of one AMC2-4WE plus a maximum of three I/O extension modules. The I/O extension modules AMC2-8IOE, AMC2-16IOE, or AMC2-16IE (in any combination) are, like the AMC2-4WE, connected via the AMC2-4W’s extension interface.

Notice! The AMC2-4WE has no display. The information about the input and outputs will be shown on special pages of the AMC2 display. As the extension modules contain neither memory nor display they are controlled and monitored entirely by the AMC2-4W. The AMC2-4W can have an additional interface extension module AMC2-4WE, so that the number of inputs and outputs can grow up to 64. Notice! An AMC2-4WE provides signals only to the AMC2 to which it is connected. Signal transfer to another AMC2 is not possible. The signal settings and parametrization of the readers connected to the extension module, are carried out by the configuration applications in the access control system and by the AMC2-4W to which it belongs.

en | Introduction
–
Each AMC2-4W controller can be extended with an AMC2-4WE extension module.
The using of AMC2-4WE modules has no influence on the limit of the maximum of controllers in one system, because it is an extension to an AMC2-4W and not a controller. Using Wiegand reader interfaces, up to four peripheral devices can be connected to each AMC2-4WE. The interfaces are pointto-point connections, meaning that only one reader can be connected to one interface.

Closing the Case Before aligning the covers, unplug any pluggable screw connectors. Insert the hooks on the lower edge of the front cover into the lugs on lower edge of the plastic back cover [1]. Please ensure that the BOSCH logo is not upside-down. The upper edge of the front cover now aligns with the two-point snap-in closures on the upper edge of the back cover [2], and may thus be clicked gently into place. Hence the closing process is the reverse of the opening process.

Notice! Risk of damage to equipment If excessive force is required to close the front cover then it is probably incorrectly hooked into the back cover. In such cases the display ’Dialog’ button in the front cover will be misaligned and will not function correctly.
4.5
Cabling Notice! Risk of malfunction The cables used in the AMC2-4WE access control system are not prone to electrical interference. However, you should avoid routing cables close to heavy load switching cables and equipment. If this is unavoidable, cross the cable at right angles every 1 to 2 m (3 to 6 ft) to reduce interference.
4.5.1
Conductor data With the calculation below you can find out which cable type must be used. If you connect the power supply and the AMCdevice with the delivered cable set from the enclosure the calculation is not necessary. For distances below 25 m (75 ft) use AWG18 conductors (1mm²). For longer distances, install an additional power supply close to the AMC2 controller. Please, calculate the voltage drop by checking the conductor specifications for characteristic resistance values. The voltage drop shall not exceed 2 V. Example: Length = 100 m/328 ft U = 12V, I = 1A, maximum UDrop = 2V
Bosch Sicherheitssysteme GmbH
2016-11 | AMC2-4WE |
24
AMC2 Wiegand Extension
en | Installing
i.e. RAWG18 (acc. specs) = 6.385 UDrop = 20,948 UDrop = 6.385
or 20,948
x 0.1 km x 1A = 2.1V x 328 ft x 1A = 2.1V
Critical condition! Install the power supply closer to the controller. Notice! These specifications apply to power supply, readers, relay outputs, and extension interface. Regarding inputs, specific voltage-drop values need to be taken into account. Refer to Connecting Analog Input Devices, page 38.

Grounding and Shielding The AMC2 controller allows you to create a central ground or shielding point, simply by setting certain jumpers. Set these jumpers only if grounding or shielding is not achieved by other means. 1.
If the AMC2-4WE has its own power - as in the third example in Overview - Power supply/consumption, page 29 - the shield will be connected to pin 2 of the power supply connector - see Connecting Diagrams, page 48.
2.
If the extension module is powered from the AMC2 controller - as in the second example in Overview - Power supply/consumption, page 29 - the connection should be made as in the RS-485 for extension modules, page 32 diagram.
3.
If more than one extension module is to be connected to an AMC2 controller, and all of them to receive power from it as well, then use the RS-485 extension interface for the connection.
Notice! In the second and third case the jumper on the bottom side of the AMC2-controller must to be set - see the installation manual of the AMC2-4W. The jumper A of the extension boards will not be set. Notice! Risk of malfunction Ensure that no ground loops are formed.
Bosch Sicherheitssysteme GmbH
2016-11 | AMC2-4WE |
26
AMC2 Wiegand Extension
en | Installing
Notice! In general the following apply: If the devices have their own power supplies, the shielding is applied to one side only. The free end should be insulated to avoid inadvertent connections. If one device is fed power by another, the cable shielding should be applied to both sides.
4.6.1
Grounding for Extension Interface
Figure 4.5: Location of ground jumper bottom side
The jumper setting A1 shows the factory settings. Jumper connects the internal ground of the AMC2-4WE to the ground of the RS-485 slave interface. Set Jumper A2 only at the first AMC2-4WE of a party line - like example four in Overview Power supply/consumption, page 29.

Tamper Protection To protect the AMC2-4WE against unauthorized access and so prevent tampering with sensitive data, the AMC2-4WE provides an additional interface to connect external tamper contacts. This interface is a potential-free 2-pin pluggable screw connector marked with T. When not in use this tamper contact should be shorted.

Status Display of the AMC2 Because the AMC2-4WE has no display of its own, the AMC2 controller displays status information about the input and output settings of the AMC2-4WE. The selected display mode remains set until the next time the button is pressed. The order of the display pages is shown in the following table. Display pages 3a to 3c include the information about the I/O-Boards’ signals. For each I/O-Board connected there is a separate display page. Push
